One method for quantitative determination of the concentration of constituents in a sample analyzed by gc is the area-normalization method. here, complete elution of all of the sample constituents is necessary. the area of each peak is then measured and corrected for differences in detector response to the different eluates. this correction involves dividing the area by an empirically determined correction factor. the concentration of the analyte is found from the ratio of its corrected area to the total corrected area of all peaks. for a chromatogram containing three peaks, the relative areas were found to be 16.4, 45.2, and 30.2 in the order of increasing retention time. calculate the percentage of each compound if the relative detector responses were 0.60, 0.78, and 0.88, respectively.
